Name ________________________________________________ Date _____________________ Period _____
Unequal Heating of Earth’s Surface: Land vs Water
Background knowledge: Specific heat of water is the amount of _______________ needed to
heat ____ gram of water by ___ degree Celsius.
In this lab, we will heat water and sand to see which gets hotter faster. Then we will remove
the heat to see whether water or sand cools faster.
1. Hypothesis: If I _____________________________________________________________________
then I think ________________________________________________________________________
because __________________________________________________________________________.
2. Draw a diagram of the lab set-up on the back of your graph paper.
3. Graph the data on the provided graph paper.
4. Analyze the data with these questions.
a. Use the phrase specific heat to explain why the water heated and cooled
differently than the sand.
b. How would having a large lake or an ocean nearby affect the climate of an
area?
5. Was your hypothesis supported by the data or evidence? List 2 specific pieces of
evidence from the lab to complete the because part of your claim.
Claim: My hypothesis was _____________________________ because ___________________
1)_________________________________________________________________________________
2)_________________________________________________________________________________
